py-juxlib

Shared Python library for the Jux tools ecosystem.

Overview

py-juxlib provides common functionality for Jux client tools:

• Environment metadata detection - Capture Git, CI/CD, and runtime environment information
• XML digital signatures - Sign and verify JUnit XML reports using XMLDSig
• API client - Publish signed reports to Jux OpenAPI servers
• Configuration management - Multi-source configuration with precedence handling
• Local storage - Filesystem storage with offline queue support
• Error handling - User-friendly errors with actionable suggestions

Installation

pip install py-juxlib

Or with uv:

uv pip install py-juxlib

Quick Start

Capture Environment Metadata

from juxlib.metadata import capture_metadata

metadata = capture_metadata()
print(f"Project: {metadata.project_name}")
print(f"Git commit: {metadata.git_commit}")
print(f"CI provider: {metadata.ci_provider}")

Sign a JUnit XML Report

from juxlib.signing import sign_xml, load_private_key
from lxml import etree

# Load your private key
key = load_private_key("~/.ssh/jux/dev-key.pem")

# Parse and sign XML
tree = etree.parse("junit-report.xml")
signed_tree = sign_xml(tree.getroot(), key)

# Write signed XML
with open("junit-report-signed.xml", "wb") as f:
    f.write(etree.tostring(signed_tree, xml_declaration=True, encoding="UTF-8"))

Publish to Jux Server

from juxlib.api import JuxAPIClient

client = JuxAPIClient(api_url="https://jux.example.com", bearer_token="your-token")

with open("junit-report-signed.xml") as f:
    response = client.publish_report(f.read())

print(f"Test run ID: {response.test_run_id}")
print(f"Success rate: {response.success_rate}%")
